Strength is the master quality.
It is the foundation for the development of the rest of the physical qualities.
Strength is a skill.
We view strength, endurance, and other qualities as skills and approach our training as "practice," not a "workout."
Strength is something to be practiced.
Workouts have their place, but as the name implies they often leave us exhausted, prone to injury, and unable to do much else.
We practice before we workout. And we practice often. Practice means to strive for good technique. Practice is done safely, and efficiently. Each repetition is strong, and technically proficient as possible. When we practice exhausted or all 'worked out' our reps are sloppy. This means ingraining a movement pattern that's not ideal.
Strength is gained quickly when we adhere to the basic principles of strength training. When we emphasize technical performance over routines, exercises, or workouts the results speak for themselves. One does not need to go 'all-out' in order to make significant gains.
What separates the master from the novice? The master knows the basics better than anyone.
Many exercises may look cool, but they are often so under-dosed that they will provide little to no actual adaptations for strength, power, hypertrophy, etc. Most people are better off sticking with the basics of strength training to reach their goals.
While standing on a Bosu ball on one leg while holding a kettlebell overhead may look impressive, basic movement patterns like traditional squatting, deadlifts, other hinges, pushes & pulls have many times more benefit overall.
